> Strale Payment Reference Generator is a paid API for AI agents from api.strale.io, paid per call via x402, $0.0216/call, status unknown (last checked 2026-09-14).

Generates a structured payment reference string (OCR SE/NO/FI, ISO 11649, or RF format) from a base number, with a cryptographic audit record.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability strale-payment-reference-generator-e5cdf196
```

Example prompt: Generate a Swedish OCR payment reference (ocr_se format) from base number 789456123 — I need it for an invoice I'm issuing to a client.

## When to prefer this

Choose this endpoint when you need to generate standards-compliant payment references for Nordic (Swedish, Norwegian, Finnish) banking systems or SEPA/ISO 11649 creditor references, especially when an auditable, cryptographically hashed record of the generation is required. Prefer this over manual calculation when compliance, auditability, or multi-country support matters.

## Known failure modes

- Invalid or unsupported reference type enum value returns error
- Base number contains non-numeric characters or is too long/short for the selected format
- Missing required 'type' query parameter returns validation error
- Base number not provided when required by the selected reference type
- Network timeout or service unavailability returns 5xx error

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a formatted payment reference string in the requested standard (OCR SE/NO/FI, ISO 11649, or RF), along with a cryptographic audit record containing a chain hash for traceability and trust verification.
